SPECIFICATION forming part of Letters Patent No. 296,217, dated April 1, 1884. Application filed October 28, 1830. (No model.)

To all whom it may concern.- I

Be it known that I, Josnrn: F. RANDALL,

of EVarren, in the county f Trumbull and State of Ohio, have invented certain new and useful Improvements in Speeders for the Man ufacture of Rovings, Coarse Yarns, &c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will. enable others skilled in the art to which it pertains to make and use it, reference being had 'to the accompanying drawings, which form part of this specification.

My invention relates to speeders for the manufacture of roving-s, coarse yarns, &c.; and it consists in the combination of the top rolls, gills, closed fliers, and two cones, the upper one of which is operated directly from the main driving-shaft, and the lower one is operated by a driving-belt from the upper cone, the driving-belt being provided with a shifting device whereby the belt can be shifted upon the cones, so that the speed of the lower cone and the spindle-shaft driven by it can be increased or diminished at will, so that as the bobbins become filled with yarn they can be made to revolve more and more slowly, so that the yarn will not be broken, as will be more fully described hereinafter.

The object of my invention is to enable the operator to control the tension of the yarn by the speed of the spindles at all times, and to gradually check their speed as the bobbins be come filled with yarn, so as to keep the tension uniform, and thus prevent the yarn from winding on the bobbin faster as it becomes filled, which would result in breaking the yarn.

In the accompanying drawings, Figure 1 is an end elevation of a spinningfmachine embodying my invention, a portion of the frame being broken away, so as to expose the mechanism. Fig. 2 is avertical cross-section, taken on the line a: a: of Fig. 3. Fig. 3 is a partial front elevation of aspinning-machine embodying my invention, a number of the spindles and their driving-gear being omitted so as to disclose the cones and their controlling devices. Figs. at and 5 are details. Fig. 6 is a top plan view of the upper cone, the belt, andits shifting mechanism detached.

A represents the frame of the machine, which policy, 0, upon its outer end, as usual.

may be of any desired construction. J ournalled at or near the center of this frame is a driving-shaft, B, which has a fast and loose Secured to this shaft, at any suitable point, is a gear-wheel, D, which meshes with the pinion E upon the shaft F, which shaft F has a mitergear, G, secured to it. Meshing with this mitor-gear G is a similar gear, H,whichis secured upon the lower end of a vertical shaft, I,which shaft has its hearings in the machine-frame, and has a second miter-gear, J, secured to its upper end. This gear J meshes with a similar gear, K, that is secured to the shaft L.

The shaft L extends along the full length of the machine, upon the top of the frame, and has secured to it a fluted lower roller, M, for every spindle that is placed in the machine. These lower rolls, M, mesh with and operate the larger top rolls, N, which are fluted in a similar manner, and which are placed upon the shaft 0. The two rolls M N just described, are placed almost over the top of the fliers, and near the rear side of the machine is another set of rolls, P Q, similarly constructed, and which sets of rolls, together with the porcupine-gills R, placed between them,

draw the sliver from the can that is placed back of the machine, and feed the yarn to the fliers. The gills serve also to straighten the fibers of the material as it passes over them, the term hacklin g beingcommonly applied to this stage in the art. 30th sets of top rolls N P, are constructed in short sections, as shown at Fig. l, so that there are only two of the rolls to each shaft, the shafts being sup ported in suitable journals upon the top of the frame, as shown at Fig. 3. In order to regulate the tension of these rolls upon the yarn, a weighted lever, S, is made to bear these levers S can be adjusted back and forth,

so as to increase or decrease the pressure at will.

The porcupine-gills R are operated by a spurwhecl, a, secured to their shafts, which wheel a meshes with wheel Z) on the shaft L. Meshing also with the wheel a is the idle-wheel c, which meshes with a larger wheel, (1, on the same shaft as the rolls Q. This train of gear ing is shown at Fig. 1. At the other end of the frame awheel, e, is fastened to the shaft L, and meshes with a large idle-wheel, f, which meshes with the wheel i on the same shaft as the wheel (I, as shown at Fig. 2.

Securedto the main shaft 13 is a gear-wheel, T, which meshes with a pinion, U, upon the flier-shaft; also secured to the shaftB is a gearwheel, WV, which meshes with a pinion, X, which is placed upon the end of the shaft, upon which the upper driving-cone, Y, is secured, and which gearsWX cause the cone to revolve. From this upper cone, Y, passes the belt Z down around the lower cone, A,which lower cone, A, has secured to one end of its shaft a pinion, B, which meshes with an idlewheel, 0, and which idle wheel in turn meshes with a pinion, D, upon the spindleshaft E. Connected with the belt Z, which passes around the cones, is a suitable shifting device, F, by means of which the belt may be moved back and forth upon the cones, for the purpose of increasing or decreasing the speed of the lower cone at the will of the operator. The upper cone, Y, being driven directly from the main shaft Z, has but one uniform movement; but as it is intended to regulate the speed of the spindles by means of the lower cone, A, the belt Z is shifted back and forth upon the two cones for this purpose.

In order to operate the shifting device, I place it upon a screw-shaft, G, which has a miter-gear, H, upon one end, and which gear H meshes with a miter-gear, I, 011 the inner end of the shaft J, which shaft has a handwheel, K, secured to its outer end. By this construction the operator can shift the belt Z, so as to cause the lower cone, A, to run faster or slower, as may be necessary.

The spindle-shaft E and the flier-shaft V both revolve in the same direction, but at different rates of speed. To the spindle-shaft are secured a series of skew-bevel gears, L, which mesh with similar gears, M, on the spindles N. These spindles 'N are supported upon a suitable step, O, which is alternately raised and lowered, so as to raise and lower the bobbins P in relation to the fliers Q in the usual man ner, whereby the yarn is enabled to be wound evenly upon the bobbins. No mechanism is here shown for raising and lowering the spindles, but any of the mechanisms well known in the art may be employed for this purpose. The gear-wheels M are feathered or otherwise suitably secured to the spindles N, so that said spindles can be raised or lowered through said gear-wheels while in revolution without interfering with their movement.

Upon the flier-shaft V are secured a series of skew-bevel wheels, R, which mesh with N, -but which wheels S are secured to the hubs of the fliers Q. While these wheels S are placed upon the spindles N they are not in any way operated by them, but receive their motion entirely from the flier-shaft V, which, as already stated, is driven by the main shaft B, and has one uniform rate of speed.

The bobbins I? have a series of holes made aroundltheircenters at eachend, in one of which holes a pin or projection from the upper ends of the spindles N catches, so as to cause the bobbins to revolve with the spindles. This being of the ordinary construction is not sh own here. WVhen the bobbins are first applied the two shafts V and E both revolve in the same direction; but theshaftVrevolves enough faster than the shaft E to cause the fliers to revolve faster than the spindles, and thus wrap the yarn upon the bobbins. As the bobbins become filled and it is desired to revolve the spindles more slowly, the operator turns the wheel K, by means of which the belt Z is shifted upon the cones and the desired object attained. If these spindles were not caused to decrease their speed the yarn wouldv be broken at some point between the rolls M N and the bobbin.

Having thus described my invention, I claim- The combination of the top rolls, porcupine or other gills, fliers, driving-shaft, the spindle-shaft, the two cones Y A, a connectingbelt, and mechanism whereby said belt may Lsimilar wheels, S, placed upon the spindles be shifted, one of the cones being operated by the driving-shaft, and the other cone serving to operate the spindle-shaft, whereby the speed of the spindles can be decreased as the bobbins become filled with yarn, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 22d day of September, 1880.

JOSEPH F. RANDALL.
